Copper Nickel Fittings

Farmer’s Copper Ltd. maintains a broad inventory of Copper Nickel C70600 (90/10) and C71500 (70/30) fittings. These copper nickel alloys prove to have very good resistance to seawater, brine water, organic compounds, neutral and alkaline salts, diluted non-oxidizing acids, and more. The copper nickel alloys are most commonly used in seawater environments because of the anti-fouling. Copper nickel creates a thin tenacious protective film formation, which eliminates any marine life to adhere to the pipe walls. Observations in velocity tests over a number of years indicates that the surface profile of copper nickel tended to become smoother rather than rougher at velocities where metal loss reached measurable amounts.

Typical Applications

• Condensers
